I have been experiencing dry mouth for a few months but it have gotten increasingly worse, this past week I have had loose stools all week with the urge to go I thought I might have a bug.. Today I was eating a bagel, my mouth felt funny to chew, when I felt my face the side by my ear, chin and mouth was swelling up. It did subside, but I have been feeling strange ever since. I think these to things are somehow related. What should I do?
